Which Dynamic Management View exposes network traffic from/to one SPID?

Question

I need to determine how much network traffic is being sent between a SQL Server 2008 R2 Dev Edition and an Ado.Net client running Win 7. I thought there should be a Dynamic Management View, but somehow I cannot find anything useful.

Answer 1

sys.dm_exec_connections:

• num_reads Number of packet reads that have occurred over this connection. Is nullable.
• num_writes Number of data packet writes that have occurred over this connection. Is nullable.
  ...
• net_packet_size Network packet size used for information and data transfer. Is nullable.
